AUTO TAB CONTROL (ATC) OWNERвЂ™S MANUAL & INSTALLATION INSTRUCTIONS IMPORTANT: This manual contains critical information directly affecting the safe and efficient operation of your boat. Please read thoroughly before operating the Auto Tab Control system. SAVE AND KEEP WITH BOAT OWNERвЂ™S INFORMATION Congratulations! You are the owner of the most sophisticated Trim Tab control system in the world. Nothing will create a more efficiently trimmed boat than the ATC. It constantly monitors your boatвЂ™s position and uses your trim tabs to maintain your optimal cruising attitude. SECTION 1 A BASIC PRODUCT UNDERSTANDING The Bennett ATC system is composed of three main components: A: ATC Keypad вЂ” The ATC Keypad enables you to turn the ATC system ON and OFF, and set the Zero Point for your boatвЂ™s best running attitude. The up and down arrows will flash showing trim tab adjustments. B: ATC Control Unit вЂ” The ATC Control Unit is a sophisticated processor and attitude sensor. It analyzes and calculates attitude readings. It вЂњlearnsвЂќ and stores the characteristics of your boat in its memory and uses this information for precise trim tab corrections. Important: The ATC Control Unit must be mounted correctly or the ATC system will not function as it should. C: Relay Module вЂ” The Relay Module Links the Hydraulic Power Unit to the Auto Tab Control system. 2 SECTION 2 BEFORE INSTALLING THE AUTO TAB CONTROL, YOU MUST CHECK THE TRIM TAB SYSTEM INSTALLATION The ATC system interfaces with the boatвЂ™s trim tab system, and automatically operates the trim tab Hydraulic Power Unit (HPU). Therefore before you install and operate the ATC system it is critical you confirm that the HPU wiring and hydraulic tubing is connected EXACTLY as described in items 1 and 2 below. 1. Hydraulic Tubing: вЂў Tubing from the port actuator must be connected to the fitting marked вЂњPвЂќ (front left) on the HPU. вЂў Tubing from the starboard actuator must be connected to the fitting marked вЂњSвЂќ (front right) on the HPU. THE TUBING MUST NOT BE REVERSED 2. Helm Control Wiring: Verify that the four-color wire harness leading to the back of the trim tab helm control is wired as follows. For Single Lever and Rocker Switch Controls Notice the indented letters on the back of the control, make sure connections are as follows: вЂў Red wire connects to вЂњRвЂќ вЂў Green wire connects to вЂњGвЂќ вЂў Blue wire connects to вЂњBвЂќ вЂў Yellow wire connects to вЂњYвЂќ For Racing Type Control Facing the control, with the word BOW at the top, turn the control over to the right (or left) and inspect the control to ensure the wiring is connected as follows: вЂў The blue wire is connected to the top two terminals вЂў The red wire is connected to the two left terminals вЂў The yellow wire is connected to the two bottom terminals вЂў The green wire is connected to the two right terminals Rocker Switch Control Single Lever Control BLUE RED POSITIVE GREEN YELLOW THE WIRING CONNECTIONS MUST NOT BE REVERSED Racing Type Control 3 For Boat Leveler Insta-Trim Systems The Auto Tab Control installation instructions are based on Bennett Trim Tab wire colors. If you are installing the Auto Tab Control on a Boat Leveler system, the wire color conversion is as follows: вЂў Bennett RED wire = Insta-Trim GREEN wire вЂў Bennett GREEN wire = Insta-Trim WHITE wire вЂў Bennett Blue wire = Insta-Trim RED wire вЂў Bennett YELLOW wire = Insta-Trim YELLOW wire FAILURE TO COMPLY WITH ITEMS 1 AND 2 ON PAGE THREE WILL CAUSE THE AUTO TAB CONTROL TO FUNCTION IMPROPERLY If you have any questions regarding items 1 and 2 contact Bennett Marine by e-mail at info@BennettTrimTabs.com or call Bennett Marine Client Services at (954) 427-1400 (8:00 a.m. - 5:00 p.m. Eastern time, Monday through Friday). SECTION 3 USING THE AUTO TAB CONTROL FOR THE FIRST TIME How to Set the Zero Point. IMPORTANT NOTE: The ATC wonвЂ™t turn on or function correctly until youвЂ™ve set the вЂњZero Point.вЂќ (If the Zero Point has not been set, the blue Set Zero light will flash.) Setting the Zero Point. After installing the system, take your boat for a test run. When underway, use the manual trim tab control to get your boat running at the best running attitude. Press and hold both вЂњSet ZeroвЂќ buttons (Sun and Moon Buttons) on the ATC Keypad (about 4 seconds) until the blue LED flashes rapidly. After the LED is flashing, release the buttons. Your boatвЂ™s attitude is now set in the memory. NOTE: The system automatically turns off as soon as youвЂ™ve set the Zero Point and released the buttons. TIP: If you cruise within a wide range of running speeds (Example: 20 to 40 mph) you should set the Zero Point within the lower half of the running range. 4 Turning the ATC on. Once youвЂ™ve set the Zero Point you can now press the ON/OFF button for 2-3 seconds to turn your ATC on. It will now take control of your trim tabs. ATC Memory. Once the Zero Point is set, the ATC will retain this attitude in memory permanently, or until it is reset. As long as the tabs are of correct size and the speed adequate, the ATC will recreate the programmed attitude regardless of changes in speed, weight distribution, sea conditions, and other variables that affect the boatвЂ™s attitude. If you want to reset the Zero Point, just follow the same procedure as above. Adjusting LED Intensity. You can adjust the brightness of the ATC LEDs using the Sun and Moon buttons for different times of day or night. These buttons are also used for setting the Zero Point. HELPFUL HINT: Most boats вЂњbreak overвЂќ (get on plane) at a particular speed. This speed is determined by weight distribution, water conditions, etc. Every boat has one particular attitude where it runs most efficiently. When you reach the best running attitude for your boat, enter it as the Zero Point. Optimal Running Attitude. A good way to reveal your boatвЂ™s optimum attitude is to conduct a test by running lightly loaded at full speed in flat water. (This should be done in an open, no traffic area.) You will confirm your boatвЂ™s ideal attitude by observing the bow in relation to the horizon, reduced bow spray, and diminished wake. 5 SECTION 4 ACTIVATING AND DEACTIVATING THE AUTO TAB CONTROL The ATC system is activated by pressing the ON/OFF button for 2-3 seconds. When the button is released, the red ON/OFF LED lights up indicating the unit is operating. Once activated, the ATC continuously analyzes and calculates the attitude of your boat and directs messages to operate the trim tabs. The ATC continues to make corrections as necessary until deactivated. The yellow LED вЂњarrowsвЂќ on the Keypad flash, indicating direction of trim tab movement. Example: When the bottom direction arrow marked PORT TAB flashes, the port trim tab is deflecting downward. Conversely, when the top direction arrow flashes, the port trim tab is retracting. The same is true for the starboard trim tab direction arrows. When one or both of the ATC KeypadвЂ™s trim tab direction arrows remains in the on mode, the ATC has determined one or more of the trim tabs has reached a limit. Unit resumes operation once the boatвЂ™s attitude changes. ONCE ACTIVATED, THE ATC SYSTEM ADJUSTS THE TRIM TABS AUTOMATICALLY UNTIL YOU DEACTIVATE IT BY EITHER: 1. PRESSING THE ATC KEYPADвЂ™S ON/OFF BUTTON (Recommended method) 2. PRESSING ANY POSITION OF THE TRIM TAB HELM CONTROL OR 3. CUTTING THE POWER SOURCE TO THE ATC SYSTEM SECTION 5 SAFETY PRECAUTIONS AND INFORMATION вЂў For bow high attitude, the ATC system should be deactivated and the trim tabs manually placed in the full-up position when running in a following sea. вЂў For bow high attitude, the ATC system should be deactivated and the trim tabs manually placed in the full-up position when running an inlet. вЂў The boat must be properly trimmed when the ATC Zero Point is set. вЂў The ATC system is programmed not to activate during sharp turns. вЂў Speed, load, and trim tab size may be such that the ATC and trim tabs are unable to trim the boat at certain speeds. вЂў Occasionally check for loose or corroded wiring connections on the ATC system and trim tab system and lubricate when necessary. вЂў To avoid component damage, when power is вЂњONвЂќ do not connect or disconnect any plugs connected into the Control Unit or any other component of the system. вЂў Take immediate action to correct any malfunction or failure of your trim tabs. вЂў Improper use of the ATC system or trim tabs can cause an accident or injury. 6 BE PRUDENT вЂ” IF IT APPEARS THE ATC SYSTEM IS CAUSING YOUR BOAT TO REACT IN AN UNDESIRABLE MANNER, STOP THE BOAT вЂ“ THEN INVESTIGATE THE PROBLEM. Trim tabs and the ATC system have a significant effect on the operation and versatility of your boat, and nobody knows your boat better than you. The best learning method is to spend time getting familiar with your boatвЂ™s reaction to the trim tabs and ATC system. Always operate your boat with safety first in mind. SECTION 6 TROUBLESHOOTING THE SYSTEM 1. Activating the ATC system causes the boat to list (lean). вЂў Trim tab tubing or wiring may be crossed. See the вЂњBefore Installing the Auto Tab ControlвЂќ section of this manual. вЂў ATC system Zero Point may be incorrectly set. 2. The boat slows or is hard to steer. It is likely that the boat is in an overtrimmed condition. The Zero Point should be reset with the bow slightly higher. 3. All LEDs on the ATC Keypad flash simultaneously. Control Unit signal is interrupted. Check Keypad cable for breaks and check firmness of connection into ATC Control Unit. 4. вЂњSET ZEROвЂќ light flashes. No Zero Point has been set. Refer to Section 3 of this manual. 5. ATC system shuts off by itself. вЂў Control Unit may be receiving low voltage (less than 7 volts). вЂў If the boat is in a severe list (greater than 26 degrees), the trim tabs will fully retract and the ATC system will automatically turn off. 6. The ATC attempts to make a particular attitude correction several times and is unable to affect the boatвЂ™s attitude. The boat may be going too slow or the trim tabs may be undersized. NOTE: The ATC attempts to make a particular attitude correction several times. It forces the trim tabs to remain in a particular corrective position until the attitude changes. If it appears the trim tabs frequently cannot correct an out-of-trim position, the trim tabs may be undersized or boat speed too low. 7 AUTO TAB CONTROL (ATC) INSTALLATION INSTRUCTIONS IMPORTANT: Plan how you will lay out the system. Consider the wire runs from the Keypad to the Control Unit. Make sure battery power is disconnected! For Non-Electronic Bennett Trim Tab Control Systems (Rocker Switch Control, Single Lever Control and Racing Type Control) (Refer to Diagram on Page 12) 5($'),567 $OLJQWKHDUURZRQWKHWRSRIWKH &RQWURO8QLWZLWKWKHGLUHFWLRQRIWKH FHQWHUOLQH.HHORIWKHERDW'RQRW NOTE: The Control Unit MUST be mounted properly for the system to work DQJOHWRZDUGVWKHERZ0RXQWLQDGU\ correctly. Mount the Control Unit with the following guidelines: ORFDWLRQRQDKRUL]RQWDOVXUIDFHIUHH RIH[FHVVLYHYLEUDWLRQ Step 1: Mounting the Control Unit вЂў Location: Mount within 6 feet of the ATC Keypad. (ATC Keypad Cable is 6' long.) %2: вЂў Minimum Vibration: Mount on a surface that is free of excessive vibration. вЂў Dry Environment: Mount the Control Unit in a dry location. вЂў Level Surface: Mount the Control Unit on a relatively level surface. It is not necessary to mount the Control Unit on a perfectly level surface, as setting the Zero Point will account for some off-level mounting. However, do not mount the Control Unit at an angle, upside down or vertically. вЂў Pointing Forward: Align the arrow on the top of the Control Unit parallel with the direction of the centerline (Keel) of the boat. 8 Step 2: Mounting the ATC Keypad вЂў Cut out the template from the last page of this manual. вЂў Tape the template to the dash where you intend to mount the Keypad. (Make sure it is within 6 feet of the Control Unit.) Check behind panel for wires or obstruction. вЂў Drill a 3/4" hole for the ATC Keypad cable and two 3/16th-inch holes for the mounting screws. вЂў Connect the ATC Keypad Cable to the Keypad. Apply a thin bead of silicone sealant around the perimeter of the Keypad back. Use the two enclosed thumb nuts to secure the Keypad to the dash. вЂў Plug the ATC Keypad Cable into the Control Unit marked вЂњATC Keypad.вЂќ You can use either of the two ATC Keypad connectors. The extra connector is for an additional Keypad for an upper station. Step 3: Connecting the ATC Power Pigtail вЂў Connect the orange wire to a 12 volt positive (+) power source that is switched вЂњonвЂќ with the ignition. вЂў Connect the black wire to ground (-). вЂў Do not plug the ATC Power Pigtail into the Control Unit yet. Step 4: Connecting the ATC Control Unit to the Trim Tab Manual Control вЂў Remove your existing Manual Control from the dash. вЂў Disconnect the Red, Green, Yellow and Blue wires from the back of the Manual Control. вЂў Do not disconnect the Orange power wire. However, replace the Orange wire in-line fuse and use the enclosed 1.5 amp fuse. вЂў Trim the wires of the enclosed 6-foot ATC 4-Color Wire Harness to length and strip the wire ends. вЂў Crimp the enclosed ring terminals to the ATC 4-color Wire Harness. вЂў Connect the wires to the back of the control вЂ” Red wire to вЂњR,вЂќ Green wire to вЂњG,вЂќ Yellow wire to вЂњY,вЂќ and Blue wire to вЂњB.вЂќ вЂў Reinstall the Manual Control. вЂў Plug the Wire Harness into the Control Unit connection marked вЂњManual Control.вЂќ 9 Step 5: Connecting the Trim Tab Wire Harness to the ATC Control Unit вЂў Cut the terminals off the ends of the existing 4-color Trim Tab Wire Harness. вЂў Strip approximately 3/16ths of an inch on each wire. Pigtail for Wire Harness (PT109) вЂў Crimp the butt splices on the Pigtail for Wire Harness (PT109) onto the Trim Tab Wire Harness, matching color to color. вЂў Plug the Pigtail for Wire Harness (PT109) into the Control Unit connection marked вЂњRelay Module.вЂќ Step 6: Mounting the Relay Module вЂў The Relay Module is best located in a dry location close to the Hydraulic Power Unit. вЂў Disconnect your Trim Tab Wire Harness from your Hydraulic Power Unit. вЂў Plug the Hydraulic Power Unit Harness into the Relay Module Pigtail Connector. вЂў Plug the Trim Tab Wire Harness (already attached to the Control Unit in Step 5 above) into the remaining Pigtail Connector coming out of the Relay Module. вЂў Attach the black wire of the Relay Module Power Connectors to ground (or to the ground stud on the back of the HPU motor) and the orange wire with the in-line 20 amp fuse to a 12 volt positive source. Step 7: System Check вЂў Plug the ATC Power Pigtail connector into the Control Unit marked вЂњPower Connection.вЂќ вЂў Turn the boat power back on. вЂў Test the trim tabs using the Manual Control. Make sure the trim tabs are working correctly. If not, check the connections on the Control Unit, the Manual Control and the Relay Module. (Remember, the right hand buttons on the Rocker Control and Racing Control operate the port trim tab and vice versa.) вЂў The ON/OFF ATC Keypad button will not activate the ATC system until the initial Zero Point is set. If you turn on the ATC at this point, the blue Zero Set LED light will flash. Refer to section 3, вЂњUsing the Auto Tab Control for the first time.вЂќ 10 Installation Instructions for Electronic Indicator Control (EIC5000) Systems IMPORTANT: If you did not purchase the Auto Tab Control set designed for the Electronic Indicator Control (EIC) you will have to contact Bennett Marine for a Wire Harness to run from the EIC Module to the ATC Control Unit. (Refer to Diagram on Page 13) Follow steps 1, 2 and 3 from the Non-Electronic Bennett Trim Tab Control Systems Instructions. Connecting the ATC Control Unit to the EIC Relay Module вЂў The EIC Relay Module has a special connector built in for the Auto Tab Control. It is the shorter of the two Wire Pigtails coming out of the module. вЂў Connect the 25-foot Wire Harness (WH100025) to this shorter Wire Pigtail. вЂў Run the Wire Harness to the Control Unit at the helm. Trim the Wire Harness to the desired length and strip the wire ends.
